    • New digital technology uses the patented Mirus field effect detector cells producing micro-electrical fields that detect disruptions caused by water and fluids. Detector cells are never in contact with the water, will not corrode and are not affected by oil or foreign debris. No moving parts, no mercury and no exposed sensors. Activates at a 2' fluid level and deactivates at a 3/4' fluid level. An eight second delay prevents false starts. Ultima switch is rated to handle pumps up to 20amps at 12 or 24 volts.
